Print Combining Strings and Numbers

Print Combining Strings and Numbers

Using print function without parentheses works with older versions of Python but is no longer supported on Python3, so you have to put the arguments inside parentheses. However, there are workarounds, as mentioned in the answers to this question. Since the support for Python2 has ended in Jan 1st 2020, the answer has been modified to be compatible with Python3.

You could do any of these (and there may be other ways):

(1)  print("First number is {} and second number is {}".format(first, second))
(1b) print("First number is {first} and number is {second}".format(first=first, second=second)) 

or

(2) print('First number is', first, 'second number is', second) 

(Note: A space will be automatically added afterwards when separated from a comma)

or

(3) print('First number %d and second number is %d' % (first, second))

or

(4) print('First number is ' + str(first) + ' second number is' + str(second))
  

Using format() (1/1b) is preferred where available.

Concatenating string and integer in Python

Modern string formatting:

"{} and {}".format("string", 1)

How can I concatenate a string and a number in Python?

Python is strongly typed. There are no implicit type conversions.

You have to do one of these:

"asd%d" % 9
"asd" + str(9)

Python strings and integer concatenation

NOTE:

The method used in this answer (backticks) is deprecated in later versions of Python 2, and removed in Python 3. Use the str() function instead.

You can use:

string = 'string'
for i in range(11):
    string +=`i`
print string

It will print string012345678910.

To get string0, string1 ..... string10 you can use this as YOU suggested:

>>> string = "string"
>>> [string+`i` for i in range(11)]

For Python 3

You can use:

string = 'string'
for i in range(11):
    string += str(i)
print string

It will print string012345678910.

To get string0, string1 ..... string10, you can use this as YOU suggested:

>>> string = "string"
>>> [string+str(i) for i in range(11)]

concatenating string and numbers Java

Its the BODMAS Rule

I am showing the Order of precedence below from Higher to Low:

B  - Bracket 
O  - Power
DM - Division and Multiplication
AS - Addition and Substraction

This works from Left to Right if the Operators are of Same precedence

Now

System.out.println("printing: " + x + y);

"printing: " : Is a String"

"+" : Is the only overloaded operator in Java which will concatenate Number to String.
As we have 2 "+" operator here, and x+y falls after the "printing:" + as already taken place, Its considering x and y as Strings too.

So the output is 2010.

System.out.println("printing: " + x * y);

Here the

"*": Has higher precedence than +

So its x*y first then printing: +

So the output is 200

Do it like this if you want 200 as output in first case:

System.out.println("printing: "+ (x+y));

The Order of precedence of Bracket is higher to Addition.

Print the concatenation of the digits of two numbers in Python

You could perhaps convert the integers to strings:

print(str(2)+str(1))

Dart : Printing integer along with string

In order to print the value of the int along with the String you need to use string interpolation:

void main() {
  int num = 5;
  print("The number is $num");
}
